DURATION: 1 HOUR, 30 MINUTESEver wondered what would happen in your own home if you were taken away, and everything inside was left to rot? The answer is revealed in this fascinating programme, which explores the strange and surprising science of decay.

For two months in summer 2011, a glass box containing a typical kitchen and garden was left to rot in full public view within Edinburgh Zoo.

The Church stands accused of collaborating with the Nazis during World War II, discriminating against homosexuals, protecting its paedophile priests and stubbornly refusing to concede that we need to promote contraception to curb the spread of Aids.

The God Who Wasn't There is a documentary by Brian Flemming about his "journey exploring Christianity".

Also explored are the questions around the ethics of indoctrinating children in schools at a young age with the fear of god and other principles of so called 'faith' ...
